Program to isololate parts of mp3 files

[Jumpingmedic]

Just what the title says! I want a program that can rip bits out of an mp3 file. There are lots of songs I love... but I love certain parts of them more than other parts. It'd be nice to edit the less liked parts out. Is there any way to do this?

Help greatly appreciated.
